TIRE son AUTOMOBILES.

To aZZ 'LU/0m it may concern:

Be it known that I, WILLIAM H. CLAY, a

useful Improvements in Tires for Antomobiles; and I do hereby declare the following to be a full, clear, and eXact description oi the invention, such as will enable others skilled in the art to which it appertains tok make and use the same.

The invention relates to improvements in tires for automobiles and other motor vehicles.

The object of the present invention is to improve the construction of tires for automobiles and the like and to provide a ksimple, practical, and comparatively inexpenu sive tire equipped with means for rendering a pneumatic tire puncture proof and provided with an elastic armor section adapted to deflect nails and similar articles to prevent the same Yfrom reaching the inner tube and capable also of affording an elastic tread to prevent the armor from aliecting the resiliency and cushioning action of the tire.

With these yand other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointedout in the claim hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages o'f the invention.

ln the drawing Figure 1 is a longitudinal sectional view of a portion of a tireconstructed in accordance with this invention, Fig. 2 is a transverse sectional view of the same. y

Like numerals of reference designate cor responding parts in the several figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 and 2 designate inner and outer tubes of a pneumatic tire, the inner tube being provided with a suitable valve 3 of the ordinary construction for enabling it to be inflated. The outer tube 2 is shown continuous as the means hereinafter described for protecting the inner tube willobviate Specification of Letters Patent. ,Patented an, 18, 1916 Application ined May 12, 1915.

the necessity of removing and repairing the same, but the outer tube may be constructed of any other desired type, such as a clencher tire if desired.

The means for protecting the inner tube comprises a circumferentially arranged tire unit consisting of a metallic ring or band 4, a circumferentially arranged approximately semi-tubular layer 5 of rubber or other' suitable material such as a combination of rubloer and 'fabric and an interposed filler section 6 located between the metallic ring or band and the elastic flexible layer 5. The circumferential strip which may be either continuous or in sections is constructed of suitable resilient sheet metal or other suitable material and it is composed of a transversely straight intermediate portion, curved outwardly extending sidel portions 7 and laterally projecting flanges 8 which constitute supporting ledges for the circumferential edges of the elastic layer 5. The circumferential ller section 6 which imparts elasticity to the tire unit is constructed of any suitable material and it presents a curved outer face to the layer 5 and its inner face conforms to the configuration of the elastic strip or band and is recessed as shown at 9 to receive the same. The circumferential layer of elastic material 5 is maintained on the laterally projecting flanges 8 of the me` tallic strip or band by a covering 10 of fabricor other fiexible material which extends around the outer face of the layer 5 and the inner face of the strip or band 4:.

kThe metallic strip or band is adapted to prevent a nail, pin, or similar article from piercing the outer portion of the tire in puncturing the inner tube, and the inclined side portions of the metallic strip or band are adapted to deflect a nail or similar instrumentl and cause the same to pass outwardly instead of inwardly. The tire protecting unit not only forms an armor for the inner tube but it increases the elasticity of a tire and enables the same to respond to the cushioning action of' the inner tube. It is adapted to increase the life and durability yof pneumatic tires vand may be readily applied to the same as a separate unit to be interposed between the inner tube and the outer tube.
